摘要： An agricultural harvester includes a straw hood having a hollow interior space for receiving material other than grain (MOG) from a threshing and separating system of the harvester and chaff from a cleaning system of the harvester. A drive system is provided for powering a straw chopper and a weed seed mill. The drive system includes a single belt positioned outside of the straw hood that is wound at least partially around (i) a straw chopper pulley that powers the straw chopper, (ii) a weed seed mill pulley that powers the weed seed mill, and (iii) a power take off shaft of the harvester that receives power from an engine or other power source of the harvester.

摘要： A method for controlling crop material speed through a rotor/cage assembly of an agricultural combine. The method includes the steps of monitoring a grain loss of the combine and adjusting an orientation of a vane coupled to the cage responsive to the grain loss, a cleaning system load and/or a straw length.

摘要： A grain pan for a combine harvester comprises a plurality of grain pan members with a closed surface grain contacting surface adapted to engage the harvested crop. More than one of the grain pan members are grain pan members comprising a first connection element and a second connection element, the first connection element being adapted to effectuate a detachable connection with the second connection element of another grain pan body member and vice versa. The grain pan members are detachably connected to each other, one behind the other via their respective first and second connection elements, in a direction substantially parallel to the main direction of grain transportation.

摘要： An agricultural harvester includes a grain processing section having a crop material handling assembly. The crop material handling assembly is driven in fore and aft oscillation by a device while permitting side to side movement. A pivotal link mechanism structurally connected to the crop material handling assembly midway between its side members and to the agricultural harvester chassis drives linear side to side movement of the crop material handling assembly while permitting fore and aft movement thereof.

摘要： A harvesting machine crop unloading spout assembly includes an unloading tube elbow terminating at a first end in a first flange that is secured to the outlet of a harvesting machine crop tank. The first flange includes one or more bearings permitting it to swivel about a swivel axis and the unloading tube elbow includes a cranked portion terminating at a second end in an opening. The spout assembly further includes a fixed member adjacent the unloading tube elbow, the unloading tube elbow connected to the fixed member by way of a pivot the axis of which coincides with the swivel axis. The spout assembly includes a rotatable drive gear and a motor drivingly engaged therewith for causing rotation of the unloading tube elbow about the swivel axis, the axis of rotation of the drive gear also coinciding with the swivel axis.

摘要： A cleaning system for a harvester has a sieve that is moveable by a drive assembly that includes a rotary drive, —an eccentric device, a transmission connected to the eccentric device and to the sieve, which transmission cyclically varies the distance between the driving point of the eccentric device and the sieve coupling during each full rotation of the rotatable output shaft of the rotary drive, wherein, due to the cyclic variation of the distance between the driving point of the eccentric device and the sieve coupling, during each reciprocating sieve movement at least one of the accelerating portion of the throw stroke, the decelerating portion of the throw stroke, the accelerating portion of the return stroke and the decelerating portion of the return stroke has a duration that is different from the duration of at least one other of the portions of the reciprocating sieve movement.

摘要： A agricultural vehicle includes a step assembly having a step and a tank that is movably mounted to the step. The step has a flat and horizontally oriented top side and an angled side extending from the top side. The tank is movably mounted to the step and is configured to move between a stowed position and a deployed position. In the stowed position of the tank, a first side of the tank is aligned with and parallel to the angled side to form a continuous angled surface. In the deployed position of the tank, a second side of the tank is aligned with and parallel to the top side to form a continuous horizontal step surface.

摘要： A cleaning system for a combine harvester includes a fan, at least one duct having an interior passageway that is positioned to receive an air stream from the fan, and a surface defined within the interior passageway of the at least one duct that is configured to restrict a volume of the flow of air passing through the at least one duct and increase a pressure of the air stream passing through the duct.

摘要： An agricultural vehicle crop feeder system having housings defining a crop passage, a conveyor assembly, a rotor, a guide plate, and one or more guide vanes extending from the guide plate. The conveyor assembly propels crop material along a feeder flow direction to the rotor. The rotor has inlet vanes that receive the crop material in a receiving region located below the rotor's axis. The leading edges of the rotor inlet vanes travel towards the receiving region on a first transverse side of the rotor axis and away from the receiving region on a second transverse side of the rotor axis. The guide plate is adjacent the receiving region. The guide vane extends into the crop passage on the first side of the rotor axis, and angled relative to the flow direction with its trailing edge closer to the first rotor axis, in the transverse direction, than the leading edge.
